-Hello World Erlang Service Sample
-==============================
-This sample demonstrates an SCA service that uses a Erlang binding
-
-The README in the samples directory (the directory above this) provides
-general instructions about building and running samples. Take a look there
-first.
-
-In order to run Erlang samples you need to have Erlang/OTP distribution installed -
-epmd binary is required in your system path. See http://erlang.org for downloads.
-
-If you just want to run it to see what happens open a command prompt, navigate
-to this sample directory and do:
-
-ant run
-
-OR if you don't have ant, on Windows do
-
-java -cp ..\..\lib\tuscany-sca-manifest.jar;target\sample-helloworld-service-erlang.jar helloworld.HelloWorldServer
-
-and on *nix do
-
-java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-helloworld-service-erlang.jar helloworld.HelloWorldServer
-
-Now the server is started you can use the helloworld-reference-erlang sample to
-exercise it.
-
-Sample Overview
----------------
-The sample provides a single component that is wired to a service with a
-Erlang binding.
-
-helloworld-service-erlang/
- src/
- main/
- java/
- helloworld/
- HelloWorldService.java - interface description for
- HelloWorldServiceComponent
- HelloWorldImpl.java - component implementation
- HelloWorldServer.java - starts the SCA Runtime and
- deploys the helloworlderlangservice
- .composite and then waits for the
- service to be called via Erlang
- resources/
- helloworlderlangservice.composite - the SCA assembly for this sample
-
- test/
- java/
- helloworld/
- HelloWorldErlangServerTestCase.java - JUnit test case
- dynaignore/ - internal Java classes for ignoring test
- in case of missing Erlang/OTP distribution
- helloworld-service.png - a pictorial representation of the
- sample .composite file
- build.xml - the Ant build file
- pom.xml - the Maven build file
-
-Building And Running The Sample Using Ant
------------------------------------------
-With the binary distribution the sample can be built and run using Ant using the
-following commands
-
-cd helloworld-service-erlang
-ant compile
-ant run
-
-You should see the following output from the run target.
-
-run:
- [java] EPMD server started
- [java] 2009-05-26 11:59:07 org.apache.tuscany.sca.node.impl.NodeImpl <init>
- [java] INFO: Creating node: helloworlderlangservice.composite
- [java] 2009-05-26 11:59:08 org.apache.tuscany.sca.node.impl.NodeImpl configureNode
- [java] 2009-05-26 11:59:08 org.apache.tuscany.sca.node.impl.NodeImpl configureNode
- [java] 2009-05-26 11:59:08 org.apache.tuscany.sca.node.impl.NodeImpl start
- [java] INFO: Starting node: helloworlderlangservice.composite
- [java] HelloWorld server started (press enter to shutdown)
-
-
-As this point the SCA service is exposed as a Erlang module via Erlang RPC which is
-started automatically by the SCA runtime. To stop the server just press
-enter.
-
-To exercise the service run up the helloworld-reference-erlang sample. Take a look at
-the README in that sample and you will see you need the following commands
-
-cd helloworld-reference-erlang
-ant run
-
-Building Sample Using Maven
--------------------------------------------
-With either the binary or source distributions the sample can be built
-using Maven as follows.
-
-cd helloworld-service-erlang
-mvn
-
-You should see the following output
-
-...
